This is a well polished game with a humorous story line, and well drawn pixel art, and the photos at the end of each round were particularly sweet. The difficulty curve sits nicely between: not too easy and not too hard; which is valuable in a game jam, because if it’s too hard I will just move on out of frustration, and if it’s too easy I’ll move on because it either stayed easy for the remainder of the game or it didn’t ramp up the difficulty soon enough.
The final boss was great fun, but it would have been nice to do something other than just avoid them the whole time, as they were pretty easy to weave around. Perhaps give them more projectiles and faster movement, minions or obstacles?
The only other improvement to make is more levels, but the number you provided is well above my expectations or what others should expect of a 48-hour game jam. If you wanted to do more polish and a couple more levels outside the time pressure, then I’m certain people would fall in love with this game, particularly if you introduce new rules for the bonds mechanic as the game progresses.
Overall, a great entry into the jam. I would be surprised if you didn’t make it into the top 100. Excellent work all!
